Gmail API status UNAUTHENTICATED

    Hi,
    I configured Post SMTP with the Gmail API, following the provided documentation.
    Right after the configuration was done, I have been able to send a couple of test messages, but since that no emails have been sent. I get the following error status:

    { "error": { "code": 401, "message": "Request is missing required authentication credential. Expected OAuth 2 access token, login cookie or other valid authentication credential. See https://developers.google.com/identity/sign-in/web/devconsole-project.", "errors": [ { "message": "Login Required.", "domain": "global", "reason": "required", "location": "Authorization", "locationType": "header" } ], "status": "UNAUTHENTICATED", "details": [ { "@type": "type.googleapis.com/google.rpc.ErrorInfo", "reason": "CREDENTIALS_MISSING", "domain": "googleapis.com", "metadata": { "method": "caribou.api.proto.MailboxService.SendMessage", "service": "gmail.googleapis.com" } } ] } }

    Everything seems to be well configured both on Post SMTP side and on Gmail side, as I was able to send test messages.

    What can make this “UNAUTHENTICATED” with “CREDENTIALS_MISSING” reason happen? Am I doing something wrong?

    Thanks in advance for any help.

    Hi,

    Thanks for your reply.
    This is almost what I did the first time, and was working for a few emails then not anymore. The only difference is that I didn’t use the assistant but set manually the settings.
    I just did the configuration again and it seems to be working for now… I’ll check whether it still works in a couple of hours and update this topic.

    Regards

    OK so it seems to be working now.
    I don’t know what’s different between the assisted configuration and the manual one but I guess I’ll go with the assistant from now on.

    Thanks for the help anyway!
